Abstract

The present invention discloses a rotor that enables an aircraft to be passively stable in hover. The rotor, having a generally fixed geometry is tiltably connected to its rotor shaft. The outer part of the rotor blades have a pitch fixed relative to the rotational plane, whereas the inner part of the rotor blades have a pitch fixed relative to a reference plane perpendicular to the rotor shaft.
